EDWARD M. BUNDGBEN, OF CHICAGO, ILLINOIS, ASSIGNOB'TO WESTERN ARCHITEC-TUBAL IRON COMPANY, OF CHICAGO, ILLINOIS.

WINDOW STRUCTURE.

Application med February 10, 1925. Serial lo. 9,884.

To all whom it may concern:

Be it known that I, EDWARD M. RUND- GREN, a citizen of the UnitedStates, and a resident of the city of Chicago, county of Cook, and Stateof Illinois, have invented certain new and useful Improvements in WindowStructures, of which the following is a specification.

My invention relates to wlndow structures, and thesame has for a mainobject the provision of an improved window construction which willembody certain desired features of simplicity, eiiciency andconvenience, which will be economical in manufacture and durable in use.

Another object of my invention is to provide an improved windowespecially adapted for use in the basements of buildings, in garages,shops and other places; one in which the sash can be readily and quicklyremoved from the frame and in which means comprising novel weather-proofelements eiectually safeguard against the wind and the rain.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference. to the accompanyingdrawings forming a part of this specification, and in Which,

Fig. 1 represents an exterior view of a window construction made inaccordance with the present invention, this view showing theconstruction as installed in a wall;

Fig. 2 represents an interior view of the window construction asinstalled in a wall;

Fig. 3 is a horizontal section taken approximately on line 3-3 of Fig.2;

Fig. 4 is a vertical section taken approximately on line 4.--4 of Fig.2; and

Fig. 5 represents a vertical sectional view through the window sash.

The preferred embodiment of my invention, as illustrated in theaccompanying drawings, includes an all-metal window frame denoted as awhole by the reference character 6 and comprising opposedmain sideplates 7 to which is welded or otherwise connected a head plate 8. Tothe main side plates 7 and the head plate 8 are secured, preferably byWelding, the angle side plates 9 and the angle head plate 10,respectively. From an inspection of Fi s. 3 and 4, it will be seen thatthe angle si e plates 9 are secured intermediate the width of the mainside plates 7, so that the outer marginal edges 7 of the main plates maybe built or fitted into the wall as 11 to which the window constructionis applied, and also that the inner marginal edges 7 of the main platesmay be utilized as abutments for the window sash as will more fullyappear hereinafter. Similarly, the head angle plate 10 is securedintermediate the width of the head plate 8, so that the outer marginaledge 8 may be built or fitted into a wall as 11 while the inner marginaledge 8" is adapted to serve as an abutment for the window sash. Theall-metal window frame is completed by weldin or otherwise securing tothe bottom en .thereof the angle sill 12, designed to be secured to orfitted upon a projecting portion 13 of the window ledge or wall 14. y

The window sash, designed to be employed in connection with the windowframe and herein designated as a whole by the `reference character 15,is an all-metal construction produced in a novel manner from T-platesand angle plates. Preferably and as shown, the sash 15 has for itsopposed sides the T-shaped side plates 16 to which are welded the angleplates 17, whose angles face outwardly of the structure as shown in Fig.3. These side T-plates and angle plates 16 and 17 are so fashioned andconnected that, upon the application of the sash to the window frame,the cross pieces of the T-plates will contact with the inner mar inaledges 7 of the main frame plates 7, w ile the outwardly projectingportions of the angle plates 17 w1ll engage over the inner extremitiesof the angle plates 9 comprising the sides of Vthe frame. The top of theWindow sash consists of an angle plate 18 which is welded in properposition upon the top ends of the T-plates 16 and angle plates 17. Thebottom portion of the window sash comprises a T-plate 19 to which issecured an angle plate 20, these parts being so arranged that, upon theapplication of the sash to the frame, the cross piece of the T-shapedplate 19 will-engage over a half-round weather strip 21 when the angleplate 20 engages over the inner marginal odge of the frame sill 12, asbest illustrated in Fig. 4. Saidweather strip 21 is preferably securedupon the frame sill 12 by welding it thereon.

According to an important feature of my invention, the sash-15 isremovably set in the window frame, provision being made whereby the sashmay be locked to and with the window frame, and provision further belngmade whereby, when unlocked, the sash may be swung relatively to theframe. From an inspection of Figs. 2 and 4 it will be seen that openbearings 22 are formed in the top ends of the side plates 9 of thewindow frame; and that there is secured u on the head angle plate 18 ofthe sash a s aft 23 which is adapted to be removably entered in saidopen bearings 22 and which is further adapted to have turning t in saidbearings. Another feature of the construction in this connection is thatthe co-acting members at the head ends of the frame and sash are soarranged that the said shaft 23, when mounted in the bearings 22, willconstitute a weather-proof strip between the head angle plate 10 of theframe and the head angle plate 18 of the sash. In applying the sash tothe frame, it is only necessary to set the shaft 23 in the bearings 22and then press the sash into its seat, pushing the sash T-plate 19 overthe bottom weather strip 21, it being evident that the shaft 23 willrise in the open bearings 22 in order to permit said T-plate to riseover the said weather strip 21. To swing the sash in the frame, it isonly necessary to draw the lower portion outwardly of the frame, slidingthe T- lshaped plate 19 over the weather strip 21.

The sash, in order to be removed from the frame, is lifted upwardly soas to withdraw the shaft 23 from its bearings.

Means are provided for drawing the sash tightly to its seat in the frameand at the same time effecting tight weather-proof contact for theweather strip 21 and the shaft 23 which, as hereinbefore observed, alsoconstitutes a weather strip. In the present embodiment, this meanscomprises a cam action latch 24 pivoted at 25 to the sash and adapted toco-act with a keeper 26 which is secured to the angle sill 12 of theframe. To this end, in the embodiment shown, the keeper 26 is made withan opening 27 having a tapering wall 28 with which the cam portion 29 ofthe latch engages in closing so as to press the sash tightly to theframe, the said cam portion 29 also being made with a hooked extremity30 designed to engage under the keeper so as to draw the sashdownwardly, bringing the shaft 23 into tight engagement between theframe angle plate l0 and the sash angle plate 18 and also bringing thecross piece of the T-plate 19 into tight engagement with theweather-proof strip 21'.

lVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not Wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.
